Specification of Letters Patent. l Patented April 14, 1908.Appiicacionied July a, 1907. serial No. 382,024.

. To all whom it may concern: l

e it known that I, CHARLES H. WILLIAMS, Jr., a citizen of the UnitedStates, residing at- `In the drawings, l indicates the brake head jhaving the 'aws laand the usual lugs usual j f 1l. In the cons ructionshown 1n Fig. 2

a j n a n y Chicago, Cook county, Illinois, have inventedn strengtheningwebs 2 integral with the brake' a certain.new and useful Improvement inBrake-Heads, of which the following is a full, clear, and exactdescription, such as will enable others skilledV in the art to which itappertains to make and use the saine, refer--l ence being had totlieaccoinpanying drawings, forming part of this speciiication, 4inwhich- Figure l is a detail view brake head; and Fig. 2 is a modifiedform of brake head. This invention relates to a new and usefulimprovement in brake heads, the object being to provide a brake headwith a strengthen-f ing rib or web across .what might be termed thethroat portion of the brake head located between the two jaws.

The brake head shown in the accompanying drawings is what is known asthe Christie head, the jaws and lugs conforming to the teinplet reuireinents as prescribed by the Master Car uildersAssociation. Brake jhead extend between the lugs 1b, while in Fig. l these strengtheningwebs aiecontinued between the lugs and the jaw members of the brake headso as to provide a continuous of my improved similar View of a o'f thebrake head said anges could project laterally from the side faces of thebrake head so as to strengthen the throat portion, but as it isdesirable to preserve the sidelines, I prefer the arrangement shown inthe drawings. Having thus described the invention, what is claimed asnew and desired to be-secured byLetters Patent is:

1'. A brake head provided on its front face with apair of key lugs, andreinforcing'webs connecting said lugs together; substantially asdescribed; 2. A brake head provided adjacent its ends with jaws, keylugslocated intermediate said 'aws, and reinforcing webs connecting said eylugs together; substantially as described. 3. A'brake head provided atits opposite ends with jaws, a pair of key lugs located inin present useare usually made of malleable iron, and in practice it has beendetermined that either from improper mounting of the brake shoe in thehead or improper setting of the brake head on the beam, the jaws of thebrake head are subjected to unusual strains which has developed alweakness inA that part of the brakev head indicated at A, which I havedesignated as the throat or connecting portion between the jaws.

Because the brake heads are made of malleable iron it is im racticabelin practice to increase the thic ness of the metal at the throatportion, due to the liability of the Inalleableized casting to crack,which cracking results from uneven shrinkage. Therefore, I pro ose toprovide a strengthening web inthe brake head, which strengthweb mayeitherextend between the key ugs or may continue beyond the key` lugs tobe lconnected to the jaws.

My invention consists in providing a brake head with a strengthening webor webs whose function is to reinforce the throat pori said lugs beingspaced away from each other, tion of the brake head so that said brakeand reinforcing webs bridging the space behead can withstand heavystrains imposed .tween said lugs; substantially as described.

- v6. A cast metal brake head comprising a connecting theV lugs togetherand also connecting the lugs and jaws together substantially asdescribed. y

4.'A cast metal brake head comprising a. body portion provided adjacentits opposite ends with jaws, key lugs arranged intermediate said jaws,and reinforcing webs formed 4integral with the body portionand bridgingthe space between said lugs; substantially as described.

5. `A cast metal brake head having a concaved front face provided with apair of integral lugs of approximately inverted U-shape,

ianges project forwardly from the front faceV reinforcement on.each sideof the face of the termediate said jaws, and reinforcing webs A bodyportion provided at its opposite en ds In testimony whereof I hereuntoeix my with jaws, a pau' of lugs of approximately msignature inl :Lnepresence of two wltnesses7 Verted U-shape on said body portion. inter-Ythis 26 day of June 1907 mediate the jaws, and reinforcing webs con-CHARLES H.
